Opentherm gateway and script integration into Homeseer

[Rebel]

Bernard,

Can you share the info to get a working gateway, the mentioned site give a almost working printsetup.
Small modifications are needed. I don't see whats going on.

Ps. a couple years ago I bought the original Remeha gateway and a Celcia 20 to get it hooked up with HS, but no luck!

Thanks in advantage

Hi all,

I did upload the latest version (02)of the script. See the opening post in this topic. I did not include the (basic) documentation yet, but added a screenshot of the devices and the events I have in Homeseer.

Rebel,

I have build the gateway with the information found on the mentioned site: http://tclcode.com/opentherm/.

[phoenixb]

I see it, thanks.
Now the next question is there someone that can made this PCB in place of making this print on a experiment board.
Grtz,

Still with great support of the developer and with the pcb factory of eurocicruits, i've managed to get a working gateway.



Unfortunatly my Intergas boiler isn't to keen on sending a lot of information compared to the Remeha boiler,

Do you happen to know if the added functionality of requesting te status of all opentherm messsages has also been inclued in the public hex images ?

Great work on the scribt btw

Cool, very very cool!

I think there will be quite a lot of members who'll be interested in how you managed eurocircuits to produce the pcb for you.
I have a half-finished perfboard version here, but actually I would prefer starting all over again with a pcb instead of finishing the perfboard version.
Did you create the necessary files for pcb production yourself, or..??

This seems to answer my quetion

I've received the schematic and board (eagle) from the developer. Didn't realy change much on the board file. Only replaced some 90 degree corners to 45 and removed the fuse in the 230V circuit.

Also created a new 'silk layer' which should have been printed on the top side of the print but instead they've used the another layer from the eagle file to print, but it's only cosmtical. Part names aren't properly aligned, but after soldering all the parts and mounting it in a box, who notices

Wow Fabians, looks Great! Good to see you have it working and the script is running as well! Your intergas boiler does give more info than my Daalderop boiler, the number of starts and operation hours is not provided via Opentherm (although this info is available via menu on the boiler).

I don't understand your last question, maybe you can rephrase? In the last picture I don't see values, did you run the script "Run script: BLB_OT_monitor_02.vb("Main","PR=all")" already?

[fabian]

did you run the script "Run script: BLB_OT_monitor_02.vb("Main","PR=all")" already?

I did.. I've created the same two (time triggered & recurring) events.
BLB_OT_monitor_02.vb("Main","PR=all")
BLB_OT_monitor_02.vb("Main","PS=1")

1st run

Code: Select all

8-2-2012 23:09:36  - OTmonitor error - communication: Conversion from string "1T10010A00" to type 'Double' is not valid.

The second time it didn't return any errors.

Devices sorted by Last changes. All other devices are "never set".

[blb]

"1T10010A00" is an output after PS=0, which is default setting. Have a look at the output of the gateway when you connect to the serial port with e.g. Putty and give the command PS=0. After you provided one time PS=1 the gateway stops with sending all direct, real time output.

Already did http://www.domoticaforum.eu/viewtopic.p ... 947#p53943

If the recurring event is started before the time triggered event, it doesn't report any errors.
Some information is sent at a realy low interval. I'll wait 24 hours and then delete all devices which havent been changed.

Did you use icons from a free icon pack or created them yourselve ?

[blb]

I did use icons from a plugin, I don't know which one anymore.....

[fabian]

Ik gok de rfxcom plugin. Als de rfxmeter opvolger nou leverbaar was zou ik de plugin ook kopen

[fabian]

If anyone else is missing the icon's, i've recreated and attached them.

While creating the temperature icon's i've noticed all default HS icons in the device list are sized 32x32 pixels and resized to 24x24 by html. So i've also made the temperature icons 32x32 and added the following to all lines containing <img in blb's vb script.

Code: Select all

width='24' height='24' align='absmiddle'

I'm getting more and more sick of my Nemfit Hvac system.
I think this Nefit will not reach an old age......
nice project Fabian!
